tail -f already does a fflush().

Also we're about to add a `stdbuf` util to control buffering of utilities, so I'm not sure that this should be applied.

when tail's stdout is not a terminal, stdio library fools us by buffering large chunks of data.
This patch adds an option to run in unbuffered mode,
Implemented as straightforward use of fflush().
